ESR Group, a new economy real asset owner and manager, and STACK Infrastructure, a digital infrastructure provider, have announced that they will jointly construct and operate a new data center as part of a multi-phase 72MW data center campus development in Japan.
In a press release, the companies revealed that the campus was being developed in Keihanna, located in Japan’s Kansai region, where construction has commenced on the first building, KIX01A, which has 18MW of IT capacity. It is expected to be ready for service in the second quarter of 2027. This facility has been pre-certified as LEED Gold for sustainable building design and construction.
Stuart Gibson, ESR Group Co-founder and Co-CEO, said, “By combining our strengths and capabilities with STACK, we can meet our hyperscale customers’ needs in a high-growth market and drive value for our investors.”
Diarmid Massey, CEO of ESR Data Centres, explained the choice of location saying, “Kansai has a growing demand for modern, energy efficient digital infrastructure. The ESR-STACK Keihanna campus will deliver state-of-the-art data center capacity, scalability, and flexibility to support hyperscalers and large enterprises in a market that is expected to witness a doubling of critical IT load capacity within the next five years.”
Pithambar (Preet) Gona, Chief Executive Officer of STACK APAC, said, “Japan remains one of the most important and fastest-growing data center markets in APAC, and our expansion into the Kansai region, combined with our existing 36MW campus in Tokyo, reflects STACK’s commitment to delivering critical capacity in strategic locations across the region.”
The joint venture on KIX01A extends ESR and STACK’s partnership in APAC, which includes a 48MW data center development in Incheon, South Korea, to support the strong demand in artificial intelligence, cloud, and 5G+ technologies. KIX01A is also part of ESR’s pipeline of four data center assets in Japan and 2GW of secured land and power across APAC. ESR’s first hyperscale site, the 25MW Cosmosquare OS1 data center in Osaka, will be ready for service in June 2025.
